# GetSubItemCount
### int GetSubItemCount(int lMsgId)
수신한 SECS 메시지에서 현재 가리키고 있는 아이템의 형식이 \*\*List(L)\*\*일 경우, 해당 List에 포함된 하위 아이템(Sub-item)의 개수를 반환합니다.
{% hint style="info" %}
GetListItemOpen()과의 차이
GetSubItemCount()는 현재 List안의 수량만 파악합니다.
GetListItemOpen()은 현재 List안의 수량을 파악하고 List를 열고 포인터는 다음 아이템으로 가게 됩니다.
{% endhint %}
Parameters
```csharp
//현재 메시지에서 하위 아이템 개수 확인
int subCount = m_gem.GetSubItemCount(lMsgId);
```
